Reading the quote "While Monero isn't made to integrate with Tor, it can be used wrapped with torsocks, if you add --p2p-bind-ip 127.0.0.1 to the bitmonerod command line." in README.md at the repo, leads me to the following questions:
- Whats the status of this TOR-support via wrapper? Is this option: fully functioning and secure to use for people with basic TOR & crypto knowledge. Or this more like an draft/proof of concept/not supported dirty hack?
It's okay if you are careful. You are going through exit nodes. Always an issue when security is involved. The likelihood that exit nodes would try to trick you with a fake Monero chain seems low at this point given that Monero is pretty small and unknown. You can deal with his by checking your top hash against trusted sites (but if you are doing that through tor as well...)
Also, the README should be updated to point out you should delete or stash your p2pstate.bin file before switching to Tor (every time!) because otherwise your node can be identified by the node ID. (By deleting the file your node will generate a new one with a random ID.)
So as you can see things are a bit rough here, but usable if you are careful.
- Are more Monero I2P-nodes needed?
Monero I2P is not working yet.
- Are more Monero TOR-nodes needed?
No one has tried running Monero as a hidden service and if they did it would be tricky to connect to it. For now it relies on connecting to clearnet nodes via exit nodes.
Not sure of the answers to your other questions so I'll let other reply.
